BMW E34 ABS Up for sale is a Working, in excellent condition BMW ABS/ASC unit. Bosch Part number-- 0 265 109 010 (0265109010). This unit is from a 95 525i, this ECU should also work with other 525i's of the same vintage, perhaps other models/years as well. But as always, check your ECU's part number to be sure this is the right one for you. These units now have to be special ordered from most dealers new for big $$ (often times over $1000!), and finding a good one second hand is getting to be a very hard chore.
